- Chapter Name:
- Chapter 8: Assembly of Viruses
- Description:
- Early Events in Retrovirus Entry: Retroviruses are double-stranded RNA viruses typically found in the respiratory and enteric (gut) systems. Mammalian orthoreovirus is the focus of this visualization. Unlike other viruses, like ...

- Chapter Name:
- Chapter 8: Assembly of Viruses
- Description:
- HIV is the virus that causes AIDS. The virus is surrounded by a membrane called the viral envelope which is studded with envelope protein, shown here in blue and red. Inside the viral particle you can see the capsule, shown in ...

- Chapter Name:
- Chapter 13: The Cell Cycle and Programmed Cell Death
- Description:
- Differential interference contrast microscopy is used here to visualize mitotic events in a lung cell grown in tissue culture. Individual chromosomes become visible as the replicated chromatin starts to condense. The two ...

- Chapter Name:
- Chapter 13: The Cell Cycle and Programmed Cell Death
- Description:
- In an early Drosophila embryo, nuclei divide rapidly and in perfect synchrony. In this experiment, both DNA and tubulin are visualized with different fluorescent dyes. After the mitotic spindle has assembled, the microtubules, ...

- Chapter Name:
- Chapter 14: Motility
- Description:
- Skeletal muscle contraction is regulated by calcium in a process called Excitation-Contraction Coupling. An action potential initiated at the neuro-muscular junction, shown as a red flash, propagates along the cell membrane and ...

- Chapter Name:
- Chapter 14: Motility
- Description:
- Microtubules are dynamic cytoskeletal polymers essential for all cells. They are made of the protein tubulin, an alpha-beta heterodimer that self assembles head-to-head making protofilaments, which themselves associate laterally ...

- Chapter Name:
- Chapter 14: Motility
- Description:
- Bacteriophage T4 consists of the head (white with honeycomb pattern) containing the viral genome, the tail (green) with a baseplate at its foot, and the long tail-fibers (purple). T4 is classified as a myovirus. The term ‘myo’ ...

- Chapter Name:
- Chapter 15: Bioenergetics
- Description:
- Life requires energy. The universal, biological fuel is a molecule called ATP or Adenosine Triphosphate. ATP stores chemical energy in the form of a high energy phosphate bond. As the name suggests, it consists of an adenosine ...
